Answer:
For the parallelogram to be a rectangle, at least one angle must be a right angle or a 90° angle, we know that:
13x + 34° + 10x + 10° = 90°
=> 13x + 10x = 90° - 34° - 10°
=> 23x = 46°
=> x = 46°/23 = 2°
Answer:5
Step-by-step explanation: remeber pemdas
first we do parenthesies(I have bad spelling)
17+6/3-7*2
then we do multiplication and divition, it matters what comes first
17+2-7*2
17+2-14

Answer:
8x = 136
Where: x = 17
Step-by-step explanation:
Joshua is writing a novel. He wrote the same number of pages each day for a 8 days. At the end of 8 days he had 136 pages complete. Write an equation relating x, the number of days, to y, the total pages.
Let the number of pages read per day = x
Hence, the number of pages after 8 days = 8 × x = 8x
Total number of pages = y= 136
Therefore:an equation relating x, the number of days, to y, the total pages.
= 136 = 8x
Solving for x
136/8 = x
x = 17
Answer:
-83
Step-by-step explanation:
so plug in 10 in 8x. So it is 10*-8 -3.
-80-3=-83
-7 is the missing exponent
